Scaling of AlN/GaN HEMT for millimeter-wave power applications

K. Harrouche, Riad Kabouche, Malek Zegaoui, F Medjdoub

In this paper, we report on AlN/GaN HEMTs for high frequency applications. Various gate lengths have been studied as a function of the gate-drain distance in order to analyze the impact on the DC, RF and power performances. Electrical characteristics of this structure for 110 nm gate length show a…

GaN-on-Silicon buffer decomposition experiment: analysis of the vertical leakage current

Matteo Borga, Matteo Meneghini, Davide Benazzi, Roland Püsche, Joff Derluyn, Idriss Abid, F Medjdoub, Gaudenzio Meneghesso, Enrico Zanoni

In this work an extensive analysis on the leakage current of three samples obtained by stopping the epitaxial growth of a GaN-on-Silicon stack is presented. We studied the current leakage behavior and the breakdown voltage as a function of the ambient temperature, as well as the trapping phenomena…

Evaporation of Gold Nanofluid Sessile Drops on Heated Substrate

Rabah Boukherroub, Julien Carlier, Souad Harmand, Ibrahim Zaaroura

In this paper, experiments investigating the evaporation of gold nanofluid droplets to evaluate the effect of the particle size (5 and 10 nm) and concentrations (1 and 4% Cv), were executed on a hydrophobic silicon substrate at different surface temperature (amb, 60 and 80 °C). A drop shape…
